Hereditary cancer-predisposing syndrome

PTCH1 · rs769680080

Strength of the evidence

There is no record yet to score this position by (a ClinVar disease classification or a genome-wide significant study). That is not the same as weak evidence.

How this is scored

4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.

What ClinVar records

Classification Likely benign for Hereditary cancer-predisposing syndrome; criteria provided, single submitter (1 of 4 stars, 1 submitter), last evaluated 2026-07-01. ClinVar record 3231032 NM_000264.5(PTCH1):c.3899A>G (p.Gln1300Arg)

Classification Conflicting classifications of pathogenicity for Hereditary cancer-predisposing syndrome, Gorlin syndrome; criteria provided, conflicting classifications (1 of 4 stars, 3 submitters), last evaluated 2025-11-03. ClinVar record 824349 NM_000264.5(PTCH1):c.3899A>T (p.Gln1300Leu)

Change history 2026-11-01: Conflicting classifications of pathogenicity → Likely benign.

What this is ClinVar's aggregate record for this position (as of its 2026-11-01 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

A/A Two copies of the version labs disagree about for Hereditary cancer-predisposing syndrome: in ClinVar, some labs call it disease-causing and others do not. A result like this should be confirmed by a medical genetic test and talked through with a doctor; consumer DNA files can misread rare variants. (ClinVar VCV000824349, criteria provided, conflicting classifications)
A/T One copy of the version labs disagree about for Hereditary cancer-predisposing syndrome: in ClinVar, some labs call it disease-causing and others do not, so what one copy means is not settled. A genetic counsellor can look at the separate records. (ClinVar VCV000824349, criteria provided, conflicting classifications)
T/T No copy of the version labs disagree about for Hereditary cancer-predisposing syndrome: in ClinVar, some labs call it disease-causing and others do not. This is the usual result. (ClinVar VCV000824349, criteria provided, conflicting classifications)
